We've had this the best part of a year. Carla just loves riding in it.

I had bought a used child seat but hated using it. - The bike felt a bit top heavy at slow speed - Getting Carla in and out was difficult - I couldn't see her as we we riding- I got heal strike- I think they would be dangerous in a crash

Yeah, I apparently rode in one of those when I was little. Picture unpadded metal arms, no foot guards, plaid vinyl seat cushion, no real safety straps--and of course no helmet. I've been told we crashed once. That might explain a lot.

Yes, my father made me a child seat for our old Ford Cortina out of wrought iron which hooked over the back of the front bench seat. He ingeniously used my elder brothers cowboy belt as the retaining device.
